Product Usage

Catalyst DC1 is a delayed strong gel catalyst, which can be used for polyurethane flexible molded foam, especially suitable for NVH field, and also used for polyurethane molding materials ;

The catalyst DC1 can be used alone or as an auxiliary catalyst in conjunction with other amine catalysts. When used as an auxiliary catalyst, there will be no significant changes in the early stage, but it will shorten the later stage. Maturation time.


Catalyst DC1 catalyst is a delayed catalyst for polyurethane foaming, which can promote the reaction of urethane (polyol-isocyanate). The DC1 catalyst can delay the polyurethane foaming time while maintaining strong back-end curing. It is especially suitable for polyurethane foam molded foams for NVH applications. The DC5LE catalyst can be used in applications that require low or no amine emissions.

Typical physical properties:

Appearance Light yellow transparent liquid
Proportion 1.19
Viscosity@25℃ mPa.s 400
Water-soluble 25℃ Insoluble
Flash point, ℃ 63


Delay the catalytic polyurethane foaming reaction and increase fluidity

Wide foaming operation process

Suitable for various TDI, T/M, MT and MDI systems and CPU elastomers, CASE fields


Catalyst DC1 catalyst can be used in polyurethane flexible foam, rigid foam and castable polyurethane CPU applications, and the reaction selectivity of specific systems is extremely flexible. Due to its versatility, the level of use of the product depends on specific processing needs and applications.

Catalyst DC1 catalyst can be used in combination with DC2 catalyst, and the use level needs to be adjusted to meet specific reactivity requirements. In the existing system, a low content of DC1 catalyst can also be used as a co-catalyst to enhance the curing of the system, but due to its delayed activity, it will not significantly change the front-end reaction.

Shelf Life:

Keep it unopened for two years

Storage and transportation:

Should be sealed and stored in a dry, cool and ventilated warehouse


200KG/bucket Storage: It is recommended to store in a dry and cool area with proper ventilation. After the original packaging, please fasten the packaging cover as soon as possible to prevent the product performance from being mixed with other substances such as waterproof grade. Store in a cool, dry place, keep the container tightly closed, and avoid contact with oxides. Do not inhale dust and avoid contact with skin and mucous membranes. Smoking, eating and drinking are prohibited in the workplace. After work, take a shower and change clothes. Store contaminated clothes separately and use them after washing. Maintain good hygiene habits. The company recommends that all polyurethane catalysts be stored in a dry and cool place with proper ventilation. All storage containers must be well sealed to avoid contact with water or other influential substances, as this may change the performance of the product in use. The storage temperature is 10°C to 30°C. Lower or higher temperatures are inappropriate and should be avoided as much as possible.
